Abstract: A dielectric insert of an electrical connector is retained within a metal shell by a plurality of latching ledges formed integrally with said insert member spaced about the periphery of the outer surface thereof and facing the trailing end during insertion into the shell member, to latchingly engage with corresponding stop surfaces defined along inside surfaces of the metal shell facing the direction opposite from the latching ledges. A lip about the periphery of the trailing end of the insert member engages the leading edge of the shell to define a second stop means, preventing insert movement in both axial directions. The insert is dimensioned for the latching projections defining the latching ledges to be compressed during insertion by bearing against the inside surfaces of the shell member until fully inserted into the shell cavity.

Abstract: Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more filtered connector inserts releasably mounted within an outer conductive shell. A plurality of filtered contact assemblies are releasably retained within the insert. Each filtered contact assembly includes an electrical contact, a filter electrically coupled to the contact, and a first grounding means electrically coupled to said filter. The filtered contact assemblies are releasably and electrically coupled to the insert when the assemblies are releasably mounted to the insert, and to the outer shell when the insert is mounted within the shell. With the invention, a grounding path is automatically provided from the filter associated with each filtered contact assembly to the outer shell to dissipate filtered interference, while allowing individual removal and replacement of each filtered contact assembly from the insert, and removal and replacement of each insert from the shell.

Abstract: An electrical connector is provided which has both transient suppression and filtering means for protecting electronic equipment from energy generated by RFI, EMI, EMP and ESD. The connector is comprised of a conductive housing member having an axially extending passageway therethrough, and a circuit assembly disposed therein, the circuit assembly including a transient suppression subassembly and a pi-network filter assembly in electrical engagement with a plurality of electrical terminals. The transient suppression subassembly is comprised of a dielectric substrate having conductive path disposed thereon, a plurality of apertures extending therethrough for receiving electrical terminal members and preferably a bidirectional diode electrically connected to the terminal members and conductive path means and grounding means. The filter assembly, comprised of capacitor and inductor members is electrically engageable with the terminal members and ground.

Abstract: Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more connector inserts removably mounted within an outer shell. The filtered insert comprises a housing means, at least a portion of which is electrically conductive; at least one electrical contact within the housing means; and filter means within the housing electrically coupled to the contact for filtering interference, and electrically coupled to the conductive housing portion for providing a grounding path from the filter means to the conductive housing portion. Means are also provided for electrically coupling the conductive housing portion of the insert to the outer shell automatically when the insert is positioned in and mounted to the shell to provide an external grounding path from the conductive housing portion to the shell.

Abstract: A filtered electrical connector comprises three main parts, a header housing in which are located a plurality of socket contacts, an apertured filter ground plate connected to ground and having located therein a number of hollow tubular filter sleeve elements corresponding to the number of socket contacts, the latter elements having stems or legs located in the filter sleeve elements and soldered thereto and a ground plate secured to the front of the housing and providing a connector between ground and the shell of a pin connection adapted to be inserted into the receptacle.

Abstract: A filtered electrical header assembly for circuit boards. The assembly includes a housing supporting a plurality of terminals, filter means electrically coupled to the terminals, grounding means coupled to the filter means, and at least one conductive fastener for attaching the grounding means to the housing, for providing a means for mounting the housing to a circuit board, and for providing a grounding path from the grounding means through the at least one fastener to the circuit board. Two embodiments are disclosed: one employing tubular filter elements surrounding conductor pins, another employing a monolithic planar capacitor in contact with conductor pins. The invention permits a filtering capability to be incorporated into a standardized header assembly without affecting standardization.

Abstract: A filtered electrical connector having low insertion loss comprises a metal shell having center and intermediate electrical contacts therein, the center contact, intermediate contact and shell being electrically isolated from each other by first and second inner dielectric members; grounded filter members; and impedance members electrically connected in series with the center and intermediate contacts. The impedance members are in inductor and resistor mounted in series to electrical terminals on a circuit board having conductive paths thereon, the circuit board being disposed within the metal shell and in electrical connection with the center and intermediate contact members. The discrete filter network provides an insertion loss to high frequency interference.

Abstract: A grounding clip is provided for grounding a filtered electrical connector having a planar capacitor, upon mounting a forward end of the connector to a ground plane of a panel. The grounding clip is secured to a mounting surface of a mounting flange of the connector and has a spring contact arm extending into a cavity of the connector to both engage a ground electrode of the planar capacitor and secure the grounding clip to the connector. An adaptor clip is also provided to be secured, if desired, to the mounting flange and the grounding clip for providing grounding if it is desired to mount the rearward end of the connector of the panel.

Abstract: A surface mount connector is disclosed for electrically and mechanically interconnecting a mother circuit board with a daughter circuit board. The connector has an elongated housing with an inverted T profile, the cross bar of which engages the mother circuit board and the leg of which has a slot to receive the daughter circuit board. A plurality of terminals are mounted in the connector, each terminal having a first portion lying exposed in the slot and a second portion exposed from the cross bar.

Abstract: A connector is disclosed for mounting integrated circuit packages onto a printed circuit board or the like. The connector has a housing which is mounted on the printed circuit board and secured thereto by the terminals it carries in at least one row of aligned and spaced apart terminals. A terminal actuating insert is mounted in the housing for each row of terminals and positioned to act directly upon the terminals of that row. The connector also includes an actuating retainer or cover member which is applied after the integrated circuit package is placed into the housing. The actuating retainer or cover member acts on the inserts to cause the terminals to be closed about the leads of the integrated circuit package and also rests against the integrated circuit package to secure it in the housing.
